While most of us are just getting used to the idea of 3D printing, scientists are already working on technological marvels that operate two dimensions deeper. Researchers at the University of Southampton recently announced that they were able to record and retrieve five dimensional digital data using a quartz crystal. The ‘Superman’ memory crystal is a futuristic storage technique with unprecedented features – including a 360 terabyte per disc data capacity, thermal stability up to 1000°C and a practically unlimited lifetime.
